As we all know, the computer needs electricity to run. After the power failure, except for the laptop with its own battery, the desktop computer will be shut down. At this time, we need to use the backup power of the computer . So what is the backup power of the computer ? How to use the computer backup power supply? The following decoration home decoration network Xiaobian will give you detailed answers, I hope everyone can help after reading.
What is a computer backup power supply?
The standby power supply of the television , that is, the uninterruptible power supply, is a system device that connects the battery to the host and converts the direct current into a commercial power through a module circuit such as a host inverter . It is mainly used to provide stable and uninterrupted power supply to a single computer, computer network system or other power electronic equipment such as solenoid valves, pressure transmitters, etc.
When the mains input is normal, the standby power supply will be supplied to the load after the mains voltage is stabilized. At this time, the standby power supply is an AC mains voltage regulator, and it also charges the internal battery ; when the mains is interrupted (accident) In case of power failure, the standby power supply immediately supplies 220V AC to the load through the inverter zero-switching conversion method, so that the load maintains normal operation and protects the load soft and hardware from damage. Standby power supplies typically provide protection against excessive voltage or low voltage.
How to use the computer backup power supply?
1. The environment of the standby power supply should be well ventilated, which is good for heat dissipation and keep the environment clean.
2, the backup power supply must not have inductive loads, such as money counters, fluorescent lamps, air conditioning equipment, etc., to avoid damage.
3. The output load control of the standby power supply is optimized at about 60%, and the reliability is the highest.
4, the backup power supply is too light (such as 1000VA standby power supply with 100VA load) may cause deep discharge of the battery, will reduce the battery life, should be avoided.
5, proper discharge, help battery activation, such as long-term non-stop power, every three months should be artificially cut off the utility power with a backup power supply with a load discharge, this can extend the battery life.
6. For most small standby power supplies, turn on the backup power supply after work. Avoid booting when starting the machine. Turn off the backup power when you turn off the work. For the backup power supply of the network equipment room, since most networks work 24 hours, the backup power supply must also Run around the clock.
7. After the backup power supply is discharged, it should be charged in time to avoid damage to the battery due to excessive self-discharge.
The above is what Xiaobian brought to you. What is the computer backup power supply? How to use the computer backup power supply? I believe that everyone has a basic understanding of how to use the computer backup power after reading this article.
